I know your Mrs is a Doc Joe and I take what both of you are saying but it has recently come to the fore (that German Doc whose 1st patient died) about the way rogue Doctors have been employed by the NHS. English tests aside I doubt if I'm the only one here who has had extreme difficulty understanding some of them.
More of an immigration / special branch type issue but it shouldn't be forgotten that the gang responsible for the Glasgow Airport outrage and failed London car bombing were Middle Easterns employed as NHS Doctors. This guy sounds a right dodgy character, stealing drugs, maiming a patient (and that's the one we know about) etc - if it was down to me I'd have a thorough investigation into the lot of them - background, lifestyle, qualifications, English language ability etc. Any not up to scratch have their work permits revoked and removed from the country.
Edit
Just seen the Docs reply I agree 99% of Doctors are highly capable, but if we can pay obscene inflated salaries to hundreds of pen pushing, target focused Managers then we should be able to afford a system that roots out the bad apples.
